TECHNICAL FIELD

This disclosure relates to detection of chemical compounds, gases, and odor. More particularly to methods and systems for detection of chemicals or gases in air samples through a portable handheld device.

BACKGROUND

The proliferation, advancement, and affordability of electronic computing devices such as smart phones, laptop computers, personal computers, digital cameras, tablets, personal digital assistants (PDAs) and other electronic devices has made powerful electronic devices more available to the general public than ever before. Advancements in detection devices capable of odor detection, chemical detection and gas detection have made some detection devices common place in homes. For example, a sensor that can indicate presence of a chemical, gas or substance of interest can be useful to identify an unacceptable level of a toxic or explosive gas. There is an unmet need by the state of the art for convenient, rapid and reliable identification or detection of chemicals, gases, compounds, substances and the like.

SUMMARY

The following presents a simplified summary of the specification in order to provide a basic understanding of some aspects of the specification. This summary is not an extensive overview of the specification. It is intended to neither identify key or critical elements of the specification nor delineate the scope of any particular implementations of the specification, or any scope of the claims. Its purpose is to present some concepts of the specification in a simplified form as a prelude to the more detailed description that is presented in this disclosure.

Systems and methods disclosed herein relate to detection of odors, chemicals and gasses via handheld electronic devices (e.g., mobile phone). A sample delivery component is coupled to an electronic processor. The sample delivery component collects a headspace of a sample. The headspace is a portion of the sample that is to be analyzed. The sample delivery component can passively and/or actively collect the headspace of a sample by drawing air, for example.

A detection component is coupled to the electronic processor and sample delivery component. The detection component can analyze the headspace. The headspace analysis can determine presence and ratio of chemical, physical, and/or visual substances the make-up the headspace. Aspects of the detection component and the electronic processor can be coupled to a computer readable memory. The memory can store known analyzed samples of chemicals, gases, and/or odors, e.g., in the form of digital signatures, hash values, or any suitable use of identifying indicia or representation. The detection component can compare the analyzed headspace to known analyzed samples in the memory to determine the source of the headspace (e.g., flower, foodstuff, alcohol, perfume, etc.) and/or associate the analyzed headspace with a known source. In another example, when an analyzed headspace is determined to be a new combination of odors, gases, and/or chemicals, then the new combination of odors, gases, and/or chemicals can be stored in the memory.

In another embodiment, the detection component can determine if the headspace is a visual gas such as smoke without comparing the headspace to samples stored in memory. In this embodiment, the detection component can visually analyze the headspace.

In another embodiment, an image detection component (e.g., camera) can capture an image of a source of the headspace. The detection component can receive the captured image and determine the source of the headspace via analysis of the captured image, the analyzed headspace, or a combination thereof.

A display component displays can display a result of the analyzed headspace. The result can be a known source (e.g., type of flower, type of perfume, etc.). The result can comprise text and/or image. In one example, a result can be saved in memory and associated with as a new odor, gas, or chemical source.

DETAILED DESCRIPTION

Various aspects or features of this disclosure are described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In this specification, numerous specific details are set forth in order to provide a thorough understanding of this disclosure. It should be understood, however, that certain aspects of disclosure may be practiced without these specific details, or with other methods, components, materials, etc. In other instances, well-known structures and devices are shown in block diagram form to facilitate describing this disclosure.

Systems and methods disclosed herein relate to detection of odors, chemicals and/or gasses via handheld electronic devices. In one implementation, a mobile device receives, determines and identifies a source of a headspace of a sample. The mobile device is an electronic computing device such as for example a smartphone, tablet, PDA, laptop, cookware with circuitry, cooking utensils with circuitry, and the like.

In one embodiment, the mobile device passively receives a sample such as chemicals, gas, or odors. The sample can be received through openings in a body of the mobile device. In another embodiment, a mobile device actively draws in the sample via a sample delivery component. The sample delivery component can include an intake device such as a fan (e.g., bladed fan, air foil fan and the like), or a manually powered pump, for example. The intake device can pull air from outside the mobile device creating a positive pressure inside the device relative to the outside pressure. This causes air to pass through the device.

A detection component, coupled to a memory and a CPU, of the mobile device can receive a sample of the air. The detection component can analyze a headspace (portion) of the sample. The detection component can detect presence and amount of chemicals in the headspace. In one implementation, the detection component can include a sensory array. The sensory array can react to various chemicals within the headspace. The reaction can cause a change in physical or electrical properties of the sensory array. In one example, absorption of the chemicals in the headspace causes physical alterations of the various sensors in the sensory array. Each sensory array can react differently to the various chemicals. A CPU can transform the reactions of the sensory array into a digital signal. The digital signal can be computed based on a statistical model. For example, in one non-limiting embodiment, an organic ultra-thin transistor chemical sensor having a channel that consists of one or a few monolayers can be employed. The organic thin film transistor chemical sensors can have nearly monolayer thin film channels that act as highly-sensitive detectors of trace levels of organic vapors and can perform quantitative vapor analysis. The organic ultra-thin film can be permeable to a chemical analyte of interest.

A memory can store digital signals associated with sources (e.g., a rose, a foodstuff, burning foodstuff, etc.). In one embodiment, the detection component compares the digital signal associated with the headspace to the stored digital signals within the memory. The detection component can then find the best match and determine the source of the headspace. In another embodiment, the mobile device can compare the digital signal associated with the headspace to a memory of a server, such as a server connected via cellular communication networks, intranet, internet or similar communication networks known in the art.

In another example, the detection component can determine that a best matched sample is not in memory. In this case, a new source is associated with the digital signal associated to the headspace. An input component can receive information about the source. The memory can store the associated source with the digital signal.

In another example, the mobile device can receive a plurality of headspaces associated with the same sample via the sample delivery component. The detection component can normalize the plurality of headspaces into a normalized headspace. The normalized headspace can be analyzed as above.

In another embodiment, input component can receive information about a source of a sample. In one example, the information can include text, location information (via global positioning satellites, user input, wireless access points, wired access points, etc.), audio information, and/or image information. The detection component can analyze the received information and the headspace to determine the source of the sample. In one implementation, the information received by the input component can narrow the possible sources to be associated with the headspace to be of a certain genus or type. For example, a voice capturing device can receive audio and determine that the audio contains a phrase such as “identify this flower”. Thus, the detection component narrows the possible sources to flowers.

In another implementation, the detection component can detect if a food substance is expired, not expired, or the quality. For example, the detection component can determine if milk or wine has gone bad by comparing an analyzed headspace's associated digital signal to a known digital signal. In one aspect, input information can be received as text or audio information such as “is this wine spoiled?” and the detection component can reduce the amount of digital signals to compare to an analyzed headspace's digital signal.

In one example, the input component can include an image capturing device (e.g., a camera) can capture an image of a source associated with a sample and send the image to the detection component. The detection component analyzed the image of the source and the headspace of the sample associated with the source. The determination of the source can be enhanced and/or speed-up through the dual analysis of the captured image and the headspace. As one example, the captured image can narrow the possible sources of the headspace. For example, a sample of the fragrance of a flower can be received and an image of the flower can be captured. The detection component can determine the headspace is associated with a flower via analysis of the image of the flower.

Some non-limiting examples of types of sensors or detectors that can be employed in connection with identification of samples include: a calorimeter, a conductivity sensor, an enzymatic sensor, a biosensor, a chemical sensor, an Enzyme-Linked Assay sensor (e.g., an Enzyme-Linked Immunosorbent Assay (ELISA) sensor), an infrared (IR) spectroscopy sensor, a Nuclear Magnetic Resonance (NMR) sensor, an optical sensor, a permittivity sensor, a gas sensor, a Radio Frequency (RF) sensor, an electronic tongue sensor, a multi-frequency RF sensor, a cantilever sensor, an acoustic wave sensor, a piezoelectric sensor, a responsive polymer-based sensor, a quartz microbalance sensor, a metal oxide sensor, an X-ray Fluorescence (XRF) sensor, a nucleic acid-based sensor (e.g., a DNA-, RNA-, or aptamer-based sensor), or a regenerable sensor.

Furthermore, it is to be appreciated that multiple modalities can be employed in connection with converging on identification of a sample. For example, image or video capture components of a mobile device can be employed to identify item(s) of interest to be analyzed, audio analysis, voice analysis, text, can be employed in connection with determining identification goals of a user as well as determining properties of items that are analyzed. A user can take an image of an item (e.g., a snack) and utter is this allergen safe? The image can be analyzed (e.g., using pattern recognition) to identify that it is a cookie as well as likely type of cookie (e.g., peanut butter). Based on the utterance, the system determines that the user is interested in ensuring that the cookie does not include items that may cause an allergic reaction (e.g., nut allergy). The electronic nose can be employed to detect presence of nuts in the cookie or any other potential allergen that might affect the user. Accordingly, the combination of pattern, voice and smell detection can provide a higher confidence level regarding item and goal determination as compared to using just one sensing modality.

Moreover, geographic location, time of day, season, etc. can also be employed in connection with facilitating identification. For example, a global positioning system (GPS) component of the mobile device can provide geographic location, and such information coupled with temporal or season information can facilitate factoring likelihood of gases, chemicals, substances, compounds, allergens or the like that have a high or low probability of presence at such location and time. If the mobile device is located in Ohio during the month of May, likelihood of certain allergens (e.g., tree and grass pollens) can be factored into a determination of presence of certain items of interest Likewise, if the mobile device is located in the Arctic Circle, and the device is located outside the likelihood of a live plant or animal being a source of an item is relatively low. In yet another example, identification of location within a particular restaurant can also be employed to facilitate item identification. If the restaurant is an Indian restaurant as compared to a steak house, the presence of certain exotic spices (e.g., turmeric, saffron, garam masala, cumin, coriander, etc.) is likely to be higher than in the steak house.

Embodiments disclosed herein can leverage multiple modalities (e.g., image or pattern recognition, location based services, web-based search tools, electronic noses, chemical sensors, audio recognition, time, date, season, location, etc.) to facilitate converging on user item identification goals as well as item identification.

Sensors can be self-cleaning (e.g., vibration, light, chemical or gas washes, etc.) as well as disposable.

In the smelling process of the human olfactory system, the initial step is to bind specific odorants to the olfactory receptor protein which triggers signal transduction in a cell. Olfactory receptors expressed in the cell membranes of olfactory receptor neurons are responsible for the detection of odorant molecules. That is, when the odorants bind to the olfactory receptors as described above, the receptors are activated. The activated olfactory receptors are the initial player in a signal transduction cascade which ultimately produces a nerve impulse which is transmitted to the brain. These olfactory receptors are members of the class A rhodopsin-like family of G protein-coupled receptors (GPCRs). In accordance with an embodiment, an olfactory receptor-functionalized transistor is provided, that is useful for a bioelectronic nose which can detect and analyze specific odorants with high selectivity, by functionalizing a nanostructure transistor with an olfactory receptor (e.g., a lipid membrane having an olfactory receptor protein is formed to cover surfaces of a source electrode, a drain electrode, and a nanostructure).

The olfactory receptor protein belongs to a family of G-protein coupled receptors and may exist over the surface of, the interior of, or the surface and interior of a lipid double membrane. An olfactory receptor membrane generally includes an ionizable cysteine residue and exists in a conformational equilibrium between biophysically activated and non-activated states. The activated and non-activated states of the olfactory receptor molecule are associated with a negatively-charged base form and a neutral acid form of cysteine, respectively. When specific odorants bind to olfactory receptor molecules, equilibrium of receptor molecules moves to an activated receptor form having negative charges. The negative charges of the olfactory receptor molecules which were changed into an activated state modulate contact resistance between metal electrode and nanostructure, leading to reduction in conductance. In accordance with an embodiment, odorant molecules can be detected highly selectively based on electrostatic perturbation of a nanostructure junction generated from a conformational change by binding odorants to olfactory receptor molecules. Thus, highly-specific detection of odorants with femtomolar sensitivity can be achieved in real time, and various and novel applications such as a highly selective artificial nose application can be achieved. In one embodiment, the nanostructure may be at least one form selected from the group consisting of nanotube, nanowire, nanorod, nanoribbon, nanofilm, and nanoball. For example, semiconductor nanowires such as silicon nanowires, and carbon nanotubes may be used, and a single-walled carbon nanotube can provide desirable high biocompatibility and device characteristics.

In another embodiment, a random network of single-walled carbon nanotubes (SWCNTs) coated with non-polar small organic molecules in conjunction with learning and pattern recognition algorithms (e.g., artificial neural networks, multi-layer perception (MLP), generalized regression neural network (GRNN), fuzzy inference systems (FIS), self-organizing map (SOM), radial bias function (RBF), genetic algorithms (GAS), neuro-fuzzy systems (NFS), adaptive resonance theory (ART) and statistical methods including, but not limited to, principal component analysis (PCA), partial least squares (PLS), multiple linear regression (MLR), principal component regression (PCR), discriminant function analysis (DFA) including linear discriminant analysis (LDA), and cluster analysis including nearest neighbor) can be employed. For example, detection of volatile compounds as biomarkers for diagnosis of medical conditions can be performed using olfactometry systems that perform odor detection through use of an array of cross-reactive sensors in conjunction with pattern recognition algorithms. Each sensor can be widely responsive to a variety of odorants. Each analyte can produce a distinct signature from an array of broadly cross-reactive sensors. This configuration allows to considerably widen the variety of compounds to which a given matrix is sensitive, to increase degree of component identification and, in specific cases, to perform an analysis of individual components in complex multi-component mixtures. Pattern recognition algorithms can then be applied to the entire set of signals, obtained concurrently from a set (e.g., one or more) of sensors in the array, in order to glean information on identity, properties and concentration of vapor exposed to the sensor array.

Referring now to FIG. 1, there is illustrated a non-limiting exemplary implementation of a mobile device 110 in accordance with various aspects of this disclosure. The mobile device 110 includes a sample delivery component 111, a detection component 120, a computer processing unit (CPU) 130, and a memory 140. The mobile device 110 provides for gathering samples, and detecting and identifying source of a sample. The mobile device 110 receives sample 116 associated with a source 114. Sample 116 can be an odor, chemical, and/or airborne fragrance given off by source 114. In one aspect, CPU 130 is capable of executing various components and/or portions of components stored in a computer readable memory 140.

The sample delivery component 111 can receive the sample 116. In one implementation, the sample delivery component 111 passively receives the sample 116 as the sample 116 diffuses. In another implementation, the sample delivery component 111 actively gathers the sample 116. For example, sample delivery component 111 can comprise an intake component that draws air into the mobile device 110 or a portion of the mobile device by creating a negative air pressure in the mobile device 110 or the portion of the mobile device relative to an external air pressure.

The sample delivery component 111 is in fluid communication with the detection component 120. Detection component 120 can receive the sample 116 and analyze a headspace of the sample 116. Detection component 120 can analyze the chemical composition of the headspace or analyze a visual aspect of the headspace.

In one implementation, detection component 120 includes a sensory array. The sensory array can comprise an array of polymer films, each polymer film of the array of polymer films can be of a slightly different type. However, it is to be appreciated that various polymer films of the array of polymer films may be of a same type. The electrical conductivity of the different types of films varies in the presence of different chemicals, so that when the array of films is exposed to a particular odor, the different films respond in a characteristic way.

In another example, the sensory array can comprise an array of transistors made out of various semiconductor materials (e.g., silicon oxide sensor). Transistors made of different materials can respond differently to different chemicals, so that the array produces a distinctive signal when exposed to an odor.

In another implementation, the detection component 120 can include visual detectors (e.g., a photoelectric detector). Visual detectors can comprise a light source and a light sensor. The light source produces a light that is aimed at the light sensor. The light sensor can determine when the light is blocked. It is to be appreciated that the detection component can comprise one or more sensors. Further, the sensors can comprise various sensors such as ionization sensors.

Detection component 120 converts the reactions of the sensory array or the visual system into a digital signal. The digital signal represents a chemical composition of the headspace. The memory 140 can store the digital signal. The detection component 120 can compare the digital signal to various other digital signals stored in memory 140 to determine an identity of a source associated with the headspace. In one implementation, detection component 120 uses at least one of a hash table, fuzzy logic, artificial neural network (ANN), or pattern recognition modules, for example, to determine an identity of a source associated with the headspace.

Now turning to FIG. 2, there illustrated is a non-limiting exemplary embodiment of a mobile device 200 capable of using input 224 to aid in detecting and/or identifying various odors, chemical compounds, aromas, and or gaseous substances. Mobile device 200 comprises a sample delivery component 211, a detection component 220, an input component 226, a computer processing unit (CPU) 230, an output component 250 and a memory 240.

In one aspect, the visual information is an image of source 204. Input component 226 can identification the image as relating to a class of objects, being a specific object, and the like. In one implementation, input component 226 determines if the image of source 204 is associated with an image stored in memory 240. For example, an image is captured and input component 226 determines if the image is an image of a flower.

Detection component 220 receives analyzed input by input component 206. The analyzed input can contain information relating to source 204 and/or sample 206. Detection component 220 applies the analyzed input to narrow and/or improve identification of source 204 associated with sample 206. For example, detection component 220 receives analyzed input containing information such as “flower” and then detection component 220 can compare the analyzed headspace to entries in memory 204 which have a class type of “flower”. Detection component 220 can limit its comparison of the digital headspace signal to entries in memory with a class association of “flower”.

In another aspect, detection component 220 can receive input 224 or analyzed input from input component 206 which contains a plurality of information relating to a source 204 and/or sample 206. For example, input 224 can contain a date field, a location field and an image field. In one aspect, input 224 can contain a date field and location field. Entries in memory 240 can have associated date ranges and location ranges. Detection component 220 can apply the input 224 to limit searchable entries. For example, a flower may be indigenous to a certain location and may only bloom during a certain date range. Detection component 220 can apply input 224 to reduce the number of possible entries.

Likewise, power supply 560 can be a battery, fuel cell or other power source. Power supply 560 can be within sample delivery component 500 or can be a power supply for a larger mobile device. In another aspect, the one or more intake apertures 511 and one or more outtake apertures 550 can comprise the same one or more outtake apertures.

Referring now to FIGS. 7-9, there are illustrated methodologies and/or flow diagrams in accordance with the disclosed subject matter. For simplicity of explanation, the methodologies are depicted and described as a series of acts. However, acts in accordance with this disclosure can occur in various orders and/or concurrently, and with other acts not presented and described herein. Furthermore, not all illustrated acts may be required to implement the methodologies in accordance with the disclosed subject matter. In addition, those skilled in the art will understand and appreciate that the methodologies could alternatively be represented as a series of interrelated states via a state diagram or events. Additionally, it should be further appreciated that the methodologies disclosed hereinafter and throughout this specification are capable of being stored on an article of manufacture to facilitate transporting and transferring such methodologies to computers. The term article of manufacture, as used herein, is intended to encompass a computer program accessible from any computer readable device or storage medium.

With reference to FIG. 7, there is illustrated a methodology 700 for determining and/or identifying a source of a sample in accordance with various aspects of this disclosure. As an example, various media applications, such as, but not limited to, mobile devices such as smart phones, tablets, PDA's, cooking utensils, and cookware can use methodology 700. Specifically, methodology 700 receives a sample and identifies the sample as associated with a source.

A mobile device can receive a sample via a sample delivery component at 702, (e.g., sample delivery component 111). For example, a fan can cause a sample to enter at least one aperture in a housing of a mobile device. In another example, a sample can passively enter at least one aperture in a housing of a mobile device at 702. As such, a mobile device can continuously monitor an airspace, such as to detect smoke or various chemical compounds in an airspace.

At 704, a headspace of the sample can be analyzed by a detection component, for example. Analysis of a headspace can include a visual analysis and/or a chemical analysis (e.g., via a sensory array).

At 706, an analyzed headspace can be compared with entries in a memory, such as memory 114. Comparison can comprise comparing substances and/or compounds in the analyzed headspace with substances and/or compounds associated with entries in a memory.

At 708, the source associated with the headspace can be identified via a detection component, such as detection component 120. The analyzed and compared headspace can be associated with a best matched entry or set of entries. For example, a hash table analysis can result in one or more entries being associated with the headspace.

At 711, the identified source can be output as a result via an output component, such as output component 250. The output result can include a name of a source or sources, images of a source or sources, and/or additional associated information. The additional associated information can include genes, definition, common location, and the like.

Turning now to FIG. 8, there is illustrated a methodology 800 for determining and/or identifying a source of a sample in accordance with various aspects of this disclosure. As an example, various media applications, such as, but not limited to, mobile devices such as smart phones, tablets, PDA's, cooking utensils, and cookware can use methodology 800. Specifically, methodology 800 receives a sample and identifies the sample as associated with a source with use of additional input.

At 802, a sample is received via a sample delivery component (e.g., sample delivery component 111). For example, a fan can cause a sample to enter at least one aperture in a housing of a mobile device. In another example, a sample can passively enter at least one aperture in a housing of a mobile device at 802. As such, a mobile device can continuously monitor an airspace, such as to detect smoke or various chemical compounds in an airspace.

At 804, input is received and/or captured via one or more input component(s), such as display 611, a microphone 620, a housing 630, and/or a camera 650. Input can comprise multiple inputs such as but not limited to user input, captured image, location information, date information, and captured audio.

At 806, a headspace of the sample and input are analyzed by a detection component, such as detection component 120, for example. In one aspect, analysis of a headspace can include a visual analysis and/or a chemical analysis (e.g., via a sensory array). In another aspect, analysis of input can include audio analysis, text analysis, image analysis, location and date analysis, for example.

At 808, the analyzed headspace and the analyzed input are compared with entries in a memory, such as memory 114, for example. Comparison can include reducing possible sources to a set of possible sources via analyzed input, such as through a hash table, fuzzy logic and the like, via components executed by a CPU, such as CPU 130. In another aspect, the analyzed headspace can be compared to the reduced set of possible sources.

At 811 a source or set of sources of the sample is determined, via a detection component, for example. In one aspect, the source or set of sources can be associated with the analyzed sample and the analyzed input. The association can be stored in memory, such as memory 114, for example.

Turning now to FIG. 9, there is illustrated a methodology 900 for determining and/or identifying a source of a sample in accordance with various aspects of this disclosure. As an example, various media applications, such as, but not limited to, mobile devices such as smart phones, tablets, PDA's, cooking utensils, and cookware can use methodology 900. Specifically, methodology 900 receives a sample and identifies the sample as associated with an entry in a data store.

At 902, a headspace of a received sample is analyzed, (e.g. by detection component 111). Analysis of a headspace can include a visual analysis and/or a chemical analysis (e.g., via a sensory array).

At 904, can analyzed headspace can be compared with entries in a server, such as server 360. In one aspect, the server can comprise a memory. The memory can contain a set of entries. Each entry of the set of entries can comprise a number of fields, such as a source name, source id, date range, location, genera, genus, class, image and the like.

At 906, a source can be determined as associated with the analyzed headspace. In one aspect, a set of source can be determined as possible sources associated with the analyzed headspace.

The systems and processes described below can be implemented within hardware, such as a single integrated circuit (IC) chip, multiple ICs, an application specific integrated circuit (ASIC), or the like. Further, the order in which some or all of the process blocks appear in each process should not be deemed limiting. Rather, it should be understood that some of the process blocks can be executed in a variety of orders that are not all of which may be explicitly illustrated herein.

FIG. 10 illustrates an embodiment of a mobile device 1000 (e.g., personal digital assistants (PDAs), audio/video devices, mobile phones, MPEG-1 Audio Layer 3 (MP3) players, personal computers, laptops, tablets, etc.) that includes various optional components in connection with functionalities disclosed herein. The mobile device 1000 includes a processor 1001 and memory 1016. The components can be electrically and/or communicatively coupled to one another to perform various functions. An intake component 1002 collects a sample (e.g., air, gas, vapor, . . . ) in connection with electronic olfactory-based identification thereof. The intake component can passively collect samples or actively (e.g., employment of a fan, suction, MEMs device, negative pressure, or any other suitable means for collection a sample). A set of sensors 1004 sense properties associated with the sample or inputs to the device 1000. The sensors 1004 can optionally include any one or more of the following: chemical sensor 1006, image sensor 1008, olfactory sensor 1011, vibration sensor 1012, or touch sensor 1014. It is to be appreciated that other suitable sensors can be employed in connection with device 1000.

Search component 1020 can be employed to allow a user to search for information, e.g., via the Internet, to augment identification of a sample. In an aspect, the search results can be ordered as a function of relevancy to the search criteria, relevancy to user preferences, or rankings associated with the search results. The search component 1020 can be implemented on a manual basis (e.g., user input), or in an automated manner. For example, the search component 1020 can regularly or constantly run searches (e.g., in the background to generate content that is relevant to a user at a current point in time).

An input component 1022 can receive information about a source (e.g., of a smell). A detection component 1026 can detect presence and amount of chemicals in the headspace, e.g., collected by the sensors 1004. The sensors 1004 can react to various chemicals within a headspace. The reaction can cause a change in physical or electrical properties of respective sensors. In one example, absorption of the chemicals in the headspace causes physical alterations of various sensors in the set of sensors. Each sensor can react differently to the various chemicals. The processor 1001 can transform the reactions of the sensory array into a digital signal. For example, the digital signal can be computed based on a statistical model. In one non-limiting embodiment, an organic ultra-thin transistor chemical sensor having a channel that consists of one or a few monolayers can be employed. The organic thin film transistor chemical sensors can have nearly monolayer thin film channels that act as highly-sensitive detectors of trace levels of organic vapors and can perform quantitative vapor analysis. The organic ultra-thin film can be permeable to a chemical analyte of interest.

An inference component 1024 can infer actions or conclusions in connection with identification of a source or compound associated with a gather sample. As used herein, the term “inference” refers generally to the process of reasoning about or inferring states of the system, environment, and/or user from a set of observations as captured via events and/or data. Inference can be employed to identify a specific context or action, or can generate a probability distribution over states, for example. The inference can be probabilistic—that is, the computation of a probability distribution over states of interest based on a consideration of data and events. Inference can also refer to techniques employed for composing higher-level events from a set of events and/or data. Such inference results in the construction of new events or actions from a set of observed events and/or stored event data, whether or not the events are correlated in close temporal proximity, and whether the events and data come from one or several event and data sources. The inference component can perform a utility-based analysis in connection with making an inference. For example, the cost of making an incorrect inference can be weighed against the benefit of making a correct inference.

Detection component 1026 can analyze chemical composition of a sample or analyze a visual aspect of the sample. Pattern recognition component 1028 can identify images captured by the device (e.g., via a camera component). Audio recognition component 1030 can identify sources of audio received by the device. The device also includes a text recognition component 1032. An analysis component 1034 analyzes information received from other components and can perform an analysis in connection with identifying source, smell, attribute, feature, composition, or the like associated with a sample.

Filtering component 1036 can employ and filter information to facilitate quickly converging on identification of source, smell, attribute, feature, composition, or the like in connection with a sample. For example, null items or features can be ruled out as potential candidates in connection with determining identification. Input component 1038 receives input, e.g., from a user. The input component 1038 can receive for example, text, typed input, verbal or audio input, image input, gesture input, or any suitable type of input for inputting information. Output component 1040 outputs results of the analyses performed herein. Display component 1042 displays results of the analyses.

With reference to FIG. 11, a suitable environment 1100 for implementing various aspects of the claimed subject matter includes a computer 1102. The computer 1102 includes a processing unit 1104, a system memory 1106, a codec 1105, and a system bus 1108. The system bus 1108 couples system components including, but not limited to, the system memory 1106 to the processing unit 1104. The processing unit 1104 can be any of various available processors. Dual microprocessors and other multiprocessor architectures also can be employed as the processing unit 1104.

The system memory 1106 includes volatile memory 1111 and non-volatile memory 1112. The basic input/output system (BIOS), containing the basic routines to transfer information between elements within the computer 1102, such as during start-up, is stored in non-volatile memory 1112. By way of illustration, and not limitation, non-volatile memory 1112 can include read only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable programmable ROM (EEPROM), or flash memory. Volatile memory 1111 includes random access memory (RAM), which acts as external cache memory.

By way of illustration and not limitation, RAM is available in many forms such as static RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDR SDRAM), and enhanced SDRAM (ESDRAM).

Computer 1102 may also include removable/non-removable, volatile/non-volatile computer storage media. FIG. 11 illustrates, for example, a disk storage 1114. Disk storage 1114 includes, but is not limited to, devices like a magnetic disk drive, solid state disk (SSD) floppy disk drive, tape drive, Zip drive, LS-110 drive, flash memory card, or memory stick. In addition, disk storage 1114 can include storage media separately or in combination with other storage media including, but not limited to, an optical disk drive such as a compact disk ROM device (CD-ROM), CD recordable drive (CD-R Drive), CD rewritable drive (CD-RW Drive) or a digital versatile disk ROM drive (DVD-ROM). To facilitate connection of the disk storage devices 1114 to the system bus 1108, a removable or non-removable interface is typically used, such as interface 1116.

It is to be appreciated that FIG. 11 describes software, software in execution, hardware, and/or software in combination with hardware that acts as an intermediary between users and the basic computer resources described in the suitable operating environment 1100. Such software includes an operating system 1118. Operating system 1118, which can be stored on disk storage 1114, acts to control and allocate resources of the computer system 1102. Applications 1120 take advantage of the management of resources by operating system 1118 through program modules 1124, and program data 1126, such as the boot/shutdown transaction table and the like, stored either in system memory 1106 or on disk storage 1114. It is to be appreciated that the claimed subject matter can be implemented with various operating systems or combinations of operating systems. For example, applications 1120 and program data 1126 can include software implementing aspects of this disclosure.

A user enters commands or information into the computer 1102 through input device(s) 1128, non-limiting examples of which can include a pointing device such as a mouse, trackball, stylus, touch pad, keyboard, microphone, joystick, game pad, satellite dish, scanner, TV tuner card, digital camera, digital video camera, electronic nose, web camera, and any other device that allows the user to interact with computer 11311. These and other input devices connect to the processing unit 1104 through the system bus 1108 via interface port(s) 1130. Interface port(s) 1130 include, for example, a serial port, a parallel port, a game port, and a universal serial bus (USB). Output device(s) 1136 use some of the same type of ports as input device(s) 1128. Thus, for example, a USB port may be used to provide input to computer 1102, and to output information from computer 1102 to an output device 1136. Output adapter 1134 is provided to illustrate that there are some output devices 1136 like monitors, speakers, and printers, among other output devices 1136, which require special adapters. The output adapters 1134 include, by way of illustration and not limitation, video and sound cards that provide a means of connection between the output device 1136 and the system bus 1108. It should be noted that other devices and/or systems of devices provide both input and output capabilities such as remote computer(s) 1138.

Computer 1102 can operate in a networked environment using logical connections to one or more remote computers, such as remote computer(s) 1138. The remote computer(s) 1138 can be a personal computer, a server, a router, a network PC, a workstation, a microprocessor based appliance, a peer device, a smart phone, a tablet, or other network node, and typically includes many of the elements described relative to computer 1102. For purposes of brevity, only a memory storage device 1140 is illustrated with remote computer(s) 1138. Remote computer(s) 1138 is logically connected to computer 1102 through a network interface 1142 and then connected via communication connection(s) 1144. Network interface 1142 encompasses wire and/or wireless communication networks such as local-area networks (LAN), wide-area networks (WAN), and cellular networks. LAN technologies include Fiber Distributed Data Interface (FDDI), Copper Distributed Data Interface (CDDI), Ethernet, Token Ring and the like. WAN technologies include, but are not limited to, point-to-point links, circuit switching networks like Integrated Services Digital Networks (ISDN) and variations thereon, packet switching networks, and Digital Subscriber Lines (DSL).

Communication connection(s) 1144 refers to the hardware/software employed to connect the network interface 1142 to the bus 1108. While communication connection 1144 is shown for illustrative clarity inside computer 1102, it can also be external to computer 1102. The hardware/software necessary for connection to the network interface 1142 includes, for exemplary purposes only, internal and external technologies such as, modems including regular telephone grade modems, cable modems and DSL modems, ISDN adapters, wired and wireless Ethernet cards, hubs, and routers.

Referring now to FIG. 12, there is illustrated a schematic block diagram of a computing environment 1200 in accordance with this specification. The system 1200 includes one or more client(s) 1202, (e.g., computers, smart phones, tablets, cameras, PDA's). The client(s) 1202 can be hardware and/or software (e.g., threads, processes, computing devices). The client(s) 1202 can house cookie(s) and/or associated contextual information by employing the specification, for example.

The system 1200 also includes one or more server(s) 1204. The server(s) 1204 can also be hardware or hardware in combination with software (e.g., threads, processes, computing devices). The servers 1204 can house threads to perform transformations of media items by employing aspects of this disclosure, for example. One possible communication between a client 1202 and a server 1204 can be in the form of a data packet adapted to be transmitted between two or more computer processes wherein data packets may include coded analyzed headspaces and/or input. The data packet can include a cookie and/or associated contextual information, for example. The system 1200 includes a communication framework 1206 (e.g., a global communication network such as the Internet) that can be employed to facilitate communications between the client(s) 1202 and the server(s) 1204.

Communications can be facilitated via a wired (including optical fiber) and/or wireless technology. The client(s) 1202 are operatively connected to one or more client data store(s) 1208 that can be employed to store information local to the client(s) 1202 (e.g., cookie(s) and/or associated contextual information). Similarly, the server(s) 1204 are operatively connected to one or more server data store(s) 1211 that can be employed to store information local to the servers 1204.

In one exemplary implementation, a client 1202 can transfer an encoded file, (e.g., encoded media item), to server 1204. Server 1204 can store the file, decode the file, or transmit the file to another client 1202. It is to be appreciated, that a client 1202 can also transfer uncompressed file to a server 1204 and server 1204 can compress the file and/or transform the file in accordance with this disclosure. Likewise, server 1204 can encode information and transmit the information via communication framework 1206 to one or more clients 1202.

The illustrated aspects of the disclosure may also be practiced in distributed computing environments where certain tasks are performed by remote processing devices that are linked through a communications network.

Moreover, it is to be appreciated that various components described herein (e.g., detection components, input components, sample delivery components, and the like) can include electrical circuit(s) that can include components and circuitry elements of suitable value in order to implement the aspects of this innovation(s). Furthermore, it can be appreciated that many of the various components can be implemented on one or more integrated circuit (IC) chips. In one exemplary implementation, a set of components can be implemented in a single IC chip. In other exemplary implementations, one or more of respective components are fabricated or implemented on separate IC chips.

What has been described above includes examples of the implementations of the present invention. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the claimed subject matter, but it is to be appreciated that many further combinations and permutations of this innovation are possible. Accordingly, the claimed subject matter is intended to embrace all such alterations, modifications, and variations that fall within the spirit and scope of the appended claims. Moreover, the above description of illustrated implementations of this disclosure, including what is described in the Abstract, is not intended to be exhaustive or to limit the disclosed implementations to the precise forms disclosed. While specific implementations and examples are described herein for illustrative purposes, various modifications are possible that are considered within the scope of such implementations and examples, as those skilled in the relevant art can recognize.

In particular and in regard to the various functions performed by the above described components, devices, circuits, systems and the like, the terms used to describe such components are intended to correspond, unless otherwise indicated, to any component which performs the specified function of the described component (e.g., a functional equivalent), even though not structurally equivalent to the disclosed structure, which performs the function in the herein illustrated exemplary aspects of the claimed subject matter. In this regard, it will also be recognized that the innovation includes a system as well as a computer-readable storage medium having computer-executable instructions for performing the acts and/or events of the various methods of the claimed subject matter.

The aforementioned systems/circuits/modules have been described with respect to interaction between several components/blocks. It can be appreciated that such systems/circuits and components/blocks can include those components or specified sub-components, some of the specified components or sub-components, and/or additional components, and according to various permutations and combinations of the foregoing. Sub-components can also be implemented as components communicatively coupled to other components rather than included within parent components (hierarchical). Additionally, it should be noted that one or more components may be combined into a single component providing aggregate functionality or divided into several separate sub-components, and any one or more middle layers, such as a management layer, may be provided to communicatively couple to such sub-components in order to provide integrated functionality. Any components described herein may also interact with one or more other components not specifically described herein but known by those of skill in the art.

Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the invention are approximations, the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements. Moreover, all ranges disclosed herein are to be understood to encompass any and all sub-ranges subsumed therein. For example, a range of “less than or equal to 11” can include any and all sub-ranges between (and including) the minimum value of zero and the maximum value of 11, that is, any and all sub-ranges having a minimum value of equal to or greater than zero and a maximum value of equal to or less than 11, e.g., 1 to 5. In certain cases, the numerical values as stated for the parameter can take on negative values.

In addition, while a particular feature of this innovation may have been disclosed with respect to only one of several implementations, such feature may be combined with one or more other features of the other implementations as may be desired and advantageous for any given or particular application. Furthermore, to the extent that the terms “includes,” “including,” “has,” “contains,” variants thereof, and other similar words are used in either the detailed description or the claims, these terms are intended to be inclusive in a manner similar to the term “comprising” as an open transition word without precluding any additional or other elements.

Reference throughout this specification to “one implementation,” or “an implementation,” means that a particular feature, structure, or characteristic described in connection with the implementation is included in at least one implementation. Thus, the appearances of the phrase “in one implementation,” or “in an implementation,” in various places throughout this specification are not necessarily all referring to the same implementation. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more implementations.

Further, references throughout this specification to an “item,” or “file,” means that a particular structure, feature or object described in connection with the implementations are not necessarily referring to the same object. Furthermore, a “file” or “item” can refer to an object of various formats.

As used in this application, the terms “component,” “module,” “system,” or the like are generally intended to refer to a computer-related entity, either hardware (e.g., a circuit), a combination of hardware and software, or an entity related to an operational machine with one or more specific functionalities. For example, a component may be, but is not limited to being, a process running on a processor (e.g., digital signal processor), a processor, an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration, both an application running on a controller and the controller can be a component. One or more components may reside within a process and/or thread of execution and a component may be localized on one computer and/or distributed between two or more computers. While separate components are depicted in various implementations, it is to be appreciated that the components may be represented in one or more common component. Further, design of the various implementations can include different component placements, component selections, etc., to achieve an optimal performance. Further, a “device” can come in the form of specially designed hardware; generalized hardware made specialized by the execution of software thereon that enables the hardware to perform specific function (e.g., media item aggregation); software stored on a computer readable medium; or a combination thereof.

Moreover, the words “example” or “exemplary” are used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other aspects or designs. Rather, use of the words “example” or “exemplary” is intended to present concepts in a concrete fashion. As used in this application, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or”. That is, unless specified otherwise, or clear from context, “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then “X employs A or B” is satisfied under any of the foregoing instances. In addition, the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form.
